A Note on Automorphisms of the Infinite-Dimensional Hypercube Graph

[摘要] We define the infinite-dimensional hypercube graph $H_{{\aleph}_{0}}$ as a graph whose vertex set is formed by the so-called singular subsets of ${\mathbb Z}\setminus\{0\}$. This graph is not connected, but it has isomorphic connected components. We show
